Mean is considered to be one of the most commonly used measures of the central tendency and is considered to be the best possible approach of ensuring that everybody will be able to indulge in the best possible decision making by perfectly analysing the data. In this particular case, everybody will be on the right track of dealing with things and the general method will be perfectly implemented by people in terms of having a clear idea about the types of data available in the industry.

Grouped data will be considered as the data which has been formulated by aggregating the individual observations of the variable into different groups and on the other hand and grouped data will be the random set of observations in the whole process.

It is very much important for people to be clear about the concept of **mean formula** so that there is no chance of any kind of issue and everybody will be able to indulge in the proper calculation of the central value of the set of numbers which can be perfectly used in terms of measuring the central tendency of the data.

Central tendency is the statistical measure that will help in recognising the entire set of data or distribution through the single value and it will also help in providing people with the exact description of the whole data. In the world of statistics, this very well means that everybody will be able to enjoy the sum of the observations very successfully so that decision-making becomes very much easy as well as efficient. Some of the very basic real-life examples might include the runs scored by a particular cricketer into the test match, mean prices of the house into a particular area which have to be calculated by the real estate agents and several other kinds of related aspects.

Following are the most vital methods of calculating the mean of the given data in terms of group data:

- Calculation of the mean can be carried out with the help of a direct method in which people need to create the table of the class interval, frequency and the product of frequency as well as class marks. After this people calculate the mean by dividing the product by the total of frequencies.
- Calculation of the mean can be carried out with the help of the assumed mean method in which people create a table of class intervals, class marks, corresponding deviations, Frequencies and the mean formula with the utilisation of dividing of the product by the total of sigma DI.
- After this people can also indulge in the calculation of the mean with the help of the step deviation method in which the deviation found from the corresponding data have to be further divided by one value which will be the step deviation system in the whole process. After this utilisation of the formula can be carried out very easily by people without any kind of hassle in the whole process.

It is also very much crucial for people to be clear about different kinds of means available in the world of mathematics like the arithmetic mean, weighted mean, geometric mean, harmonic mean and various other kinds of options so that everybody will be on the right track of indulging into accurate calculations that every step which will ultimately provide them with the best possible opportunity of scoring well in the exam. Hence, having a clear idea about the **measures of central tendency** with the help of experts at **Cuemath** is the best approach to ensuring that everybody will be on the right track of making the best possible decisions at all times.
